Some days are boring. And then some days, Hilary Duff drops a throbbing synth-pop cover of a Fleetwood Mac classic. Fortunately, today (Dec. 16) belongs in the latter category.

The Breathe In. Breathe Out. star covered the band’s “Little Lies” for season two of her TV Land show Younger, and an extended version of the song has hit the Internet. You didn’t think Duff could go full-on twisty dubstep on the breakdown? You underestimated her, then.

The second season of Younger premieres on Jan. 13, 2016. Duff’s long-awaited musical comeback, Breathe In. Breathe Out., was released in June; click here to see why her single “Sparks” should have been a smash in 2015.
